Overview
2015 TD323 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 TD323 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2015 TD323 orbits the sun every 750 days (2.05 years), coming as close as 0.60 AU and reaching as far as 2.64 AU from the sun. 2015 TD323 is about 0.3 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.
Close Approaches
2015 TD323's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
2015 TD323 has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 5, 2161 | 15,678,559 | 32.469 |
